摘要

A sliding load for calibrating a microwave network analyzer provides for alignment of its center conductor (13) relative to a reference plane defined by its outer conductor (11). The sliding load includes a latching assembly (33) which in an unlatched condition allows the center conductor (13) to move freely in an axial direction relative to the outer conductor (11). The center conductor (13) can then project forward of the outer conductor (11) for visual alignment with a mating center conductor (31) of a network analyzer connector. Once the center conductor (13,31) are mated, the outer conductor (11) of the sliding load and the connector can be butted at the reference plane. The latching assembly (11,19) can then be rotated into its latched condition in which a spring is compressed (41). The compressed spring (41) forces the center conductor (13) to retract against a screw stop (43). The screw stop (43) is adjusted so that when the center conductor (13) is forced against it, the desired alignment of the center conductor (13) and the reference plate is achieved. As a result of this alignment, the sliding load does not obscure or exaggerate the contribution of network analyzer connector setback to changes in signals transmitted by the network analyzer. Thus, the network analyzer can be more accurately characterized and calibrated so that it, in turn, can characterize devices under test more precisely.
